Nurse Jennifer Gallagher, who helped treat victims of the Aurora theater shooting in Colorado, has drowned while on a family vacation in Iowa.

Gallagher, 46, of Denver, went swimming in West Lake Okoboji the night of Aug. 6 and her body was found the next day, according to the Sheriff's Office in Dickinson County, Iowa.

Gallagher, an Ireland native, worked at the University of Colorado Hospital for 13 years and cared especially for a shooting victim treated in the hospital's neurological intensive care unit, which she helped open. She was among staffers who met with President Barack Obama during his visit two days after the July 20 shooting rampage that killed 12 and wounded 58 at the Century Aurora 16 theater.

Wynonna Judd's husband, Cactus Moser, will be dealing with the effects of his Aug. 18 motorcycle crash for the rest of his life. Judd's rep tells Us Weekly that Moser's left leg was "severed at the scene of the accident," and doctors at a Rapid City, S.D., hospital decided they would have to amputate the limb above the musician's knee.

"The outpouring of prayer and support from friends, family and fans has been a blessing to both Cactus and I. Cactus is a champion," Judd told Us in a statement over the weekend. "I love him deeply and I will not leave his side."
